When this tool helps

  • Email or form uploads reject your photo for being too large
  • You want WhatsApp / social shares that load faster on mobile data
  • You need a smaller WebP or JPEG copy without installing desktop software

Practical tips

  • Try WebP first for the best size/quality balance on modern browsers
  • Keep quality around 70–85% for everyday photos, then lower only if needed
  • Always keep the original master file; compress sharing copies only

Compression runs in your browser. ToolPriv is not designed to upload your photos to a ToolPriv file server to finish this job.

Details that save time

Start with the real limit of the destination (email provider, CMS, or form). Compressing blindly until the picture looks muddy is a common mistake.

If dimensions are larger than needed, resize first. Removing unused pixels often saves more than crushing quality alone.

For screenshots with text, prefer PNG or a higher JPEG quality so UI labels stay readable.

Frequently asked questions

Is this image compressor really free?

Yes. ToolPriv is free with no account. Optional ads help keep tools free.

Do you upload my photos to a server?

No. Compression runs in your browser. Files are not sent to ToolPriv servers. Site analytics/ads cookies (if you accept) are separate from your file processing.

How is this different from upload-based compressors?

Many sites ask you to upload photos to their servers. ToolPriv compresses locally on your device, so your images never leave your browser for processing.

What formats are supported?

JPEG, PNG, WebP, and HEIC/HEIF. Output can be WebP, JPEG, or PNG.

Does it work on mobile?

Yes. Use Chrome or Safari on your phone — add photos from your gallery, compress, and download.

Is there a file size or batch limit?

Limits depend on your device memory. Typical phone photos compress fine in batches; very large RAW or ultra-high-res files may be slow on older phones.

Will quality look bad after compressing?

You control the quality slider. Start around 70–85% for WhatsApp/email; raise it if you need sharper results, or lower it for smaller files.

Do I need an account to use ToolPriv?

No signup and no login. Open the page, compress, and download.
